nuclear degneracy: atom: $2I+1$data for $I$nuclear spin number molecule: totoal degeneracy: $(2I_1+1)(2I_2+1)$ for homonuclear molecule: $I(2I+1)$antisymmetric, $(I+1)(2I+1)$symmetric examples:
$N$: $I=1,\, g_N=2I+1=3$
$N_2$: 3 antisymmetric, 6 symmetric
$NO$: $I_1=1$, $I_2=0$, $3\times1=3$
electronic degeneracy: atom: $\Sigma_J(2J+1),\, J=|L-S|...L+S$ molecule: $^{2S+1}\Lambda_\Omega$, $\phi=1$ for $\Omega=0=\Sigma$ $\phi= 2$ for $\Omega=1,2,..=\Pi,\Delta,...$. Total degeneracy = $(2S+1)\phi=\Sigma_{\Omega}(2S+1)$ examples:
$N: \, ^4S \quad S=3/2,\, L =0,\, J=3/2 \quad g_{elec}=4$

It has been more than a year since I came to the graduate school. It’s hard to say how’s the lift in u.s. but one thing I can confirm is money is everything. Everybody could devote themselves, their dream for funding. It’s really a tragedy. Hope I can get UMICH’s PhD offer even if it seems hopeless now ToT.
This post is mainly about how to configure matlab for pbs or torque configured cluster.

The following code is used for MPI parallel computing. The main purpose of the code is used to pack discontinuous data and scatter them averagely to other process.
for example:
In Zero process:
sendvar is a matrix, the size of it is 4 * 8, the data is below
1 2 3 4 5 6 7 8 11 12 13 14 15 16 17 18 21 22 23 24 25 26 27 28 31 32 33 34 35 36 37 38 the number of process is npros, npros=2
